Emergency notification apparatus

An emergency notification apparatus used in a vehicle, the emergency notification apparatus comprising:

• a position detector that sequentially detects a position of a subject vehicle, wherein the position detector is configured to detect the position of the subject vehicle based on a positioning signal received from a positioning satellite and detect the position of the subject vehicle by inertial navigation;
• a notification portion that issues an emergency notification when a state of emergency is caused in the subject vehicle;
• a map information acquisition portion that acquires map information around the subject vehicle from an outside of the subject vehicle in response to a total number of positioning satellites whose positioning signal is received being smaller than a specified value;
• and
• a correction portion that sequentially corrects the position of the subject vehicle by sequentially performing map matching between a road indicated by the map information acquired by the map information acquisition portion and the position of the subject vehicle detected by the inertial navigation in response to the number of the positioning satellites whose positioning signal is received being smaller than the specified value,
• wherein:
• the notification portion issues the emergency notification that includes the position of the subject vehicle corrected by the correction portion in a case where (i) the state of emergency of the subject vehicle has been caused in the subject vehicle, and (ii) the correction portion sequentially corrects the position of the subject vehicle.
